The Hitec

Diesel Rotary UPS system

The Hitec DRUPS system

• A complete solution that utilises

stored mechanical energy

to provide continuous power.

• Combines the functionality of

both a UPS and a Standby Diesel Engine in a single module.

• Provides high quality power to support all types of load,

including critical cooling loads and those with a leading

power factor i.e. Blade Servers.

• Suitable for both HV and LV and 50/60 Hz applications.

• A highly reliable tried and tested design.

• Minimal build cost

• UTI Tier III / TIA 942 Certified

• 3000m² of raised floor

• Load to increase over time (3-4 Year Build-out)

• Initial floor loading of 750 Watts/m²

• Ultimate floor loading 1500 Watts/m²

• Pay as you go approach to infrastructure

• Was fully designed around SUPS plus standby generators

The Original Scheme

Floor plan and plantroom take-up

for the SUPS and diesel generator scheme

Issues with the SUPS and diesel generator scheme:

• Cost and availability of the 22kV to 415V transformers

• Restricted space for up to 5 standby diesel generators

• Cooling (recirculation) issues for the diesel generators

• Very high nominal (In) and short-circuit (Isc) currents

• Reliability, control and cost of the ATS switches

• Capacity, quantity and space required for the reticulation

• LV switchgear expanding beyond the available space

• Space and cooling required for the SUPS and batteries

• Chillers unsported by UPS power

The Original Scheme

The DRUPS challenge!

• Resolve the transformer delivery issue

• Rationalise the distribution scheme, reduce reticulation

• Remove the ATS control and reduce high fault currents

• Support (if possible increase) the avialable UPS power

• Provide continuous power to the chillers

• Reduce the total building load and increase efficiency

• Resolve the spatial and cooling issues with the generators

• If possible increase useable raised floor area

• Deliver a scalable solution – Pay as you Grow!

*Cooling Load is less for DRUPS as it requires no AC and can operate at ambient

Reducing the Building Load SUPS versus DRUPS

Ventialtion and cooling Reverse the modules, remotely sited radiators and a plantroom approach

Space and Expansion Individual fire rated DRUPS rooms, seperate switchgear rooms, redundant control and rooms

Original SUPS Requirement

• 12 x 500 kVA SUPS Modules 2(4 +1)

• 5 x 2.5 MVA Standby Diesel Generators (N+1)

Alternative DRUPS Requirement

• 5 x 2.3 MVA DRUPS Modules (N+1)

Reducing CAPEX Comprehensive evaluation of approaches

Tier Classification: • System component redundancy:

N+1 requirement: for both UPS and Generation equipment, as site Generation is considered to be the primary power source.

• Multiple distribution paths, enabling…

• Concurrent Maintainability: “Any component necessary to support the IT processing environment can be maintained without impact on the IT environment.”

But… • System not ‘Fault Tolerant’:

“The site is susceptible to disruption from unplanned activities.”
